What is in the filecounted 2026-09-01

Three CSV files from one named seal day, plus a manifest with a hash of each file. Every data row has four extra fields: the quoted allow-sentence, the page we read it on, the date we read it, and a credit line. Montgomery County rows also carry the County's required disclaimer, character for character.
